This bulletin applies to 2012 Chevy Camaro models. The technician may find DTC P062F set in the ECM. This DTC may either be active or in history.
This code is falsely set during a low battery condition. This can also trigger certain HO2S heater sensor codes (P0030, P0036, P0050, P0053, P0054, P0056, P0059, P0060, P0135, P0141, P0155, P0161).
Do not diagnose the HO2S heater sensor codes until the P062F has been corrected.
If only these codes are set and the vehicle is not experiencing low battery symptoms, clear the DTCs and perform a couple of engine starts, allowing the engine to run for one minute, then shut down and allow the ECM to power down for about one minute. Restart the engine.
If no DTCs reset, no further action is needed. If the DTCs reset, check the ECM power and ground circuits, as low voltage to the ECM can cause these DTCs to set.
